| Abstract: | In situ analysis of Mn, Fe, Co, Ni and Cu in metal nodule by an isotope excited Xray fluorescence analyzer using partial least square (PLS) algorithm is reported in this paper. Performance and reliability test on the equipment and method are also discussed. The method has been applied to the determination of these elements in metal nodule national standard reference samples. The results are in agreement with certified values with precision of < 1.0% RSD (n=42) for all these elements and indicate that the method can meet the requirements of on site analysis in mineral survey.\=\= |
